scons: wait on subprocess' completion

Windows doesn't allow you to move a file that's opened, and Popen()
doesn't wait on its subprocess' completion before returning, which leads
to broken Windows build.

mesa: Require mipmap completeness for glCopyImageSubData() at times.

This patch makes glCopyImageSubData require mipmap completeness when the
texture object's built-in sampler object has a mipmapping MinFilter.
This is apparently the de facto behavior and mandated by Android's CTS.

One exception is that we ignore format based completeness rules
(specifically integer formats with linear filtering), as this is
also the de facto behavior that until recently was mandated by the
OpenGL 4.5 CTS.

This was discussed with both the OpenGL and OpenGL ES working groups,
and while everyone agrees this behavior is unfortunate and complicated,
it is what it is at this point.  There was little appetite for relaxing
restrictions given that all conformant Android drivers followed the
mipmapping rule, and all conformant GL 4.5 implementations ignored the
integer/linear rule.

i965/dri: Support R8G8B8A8 and R8G8B8X8 configs

The Android framework requires support for EGLConfigs with
HAL_PIXEL_FORMAT_RGBX_8888 and HAL_PIXEL_FORMAT_RGBA_8888.

Even though all RGBX formats are disabled on gen9 by
brw_surface_formats.c, the new configs work correctly on Broxton thanks
to _mesa_format_fallback_rgbx_to_rgba().

On GLX, this creates no new configs, and therefore breaks no existing
apps. See in-patch comments for explanation. I tested with glxinfo and
glxgears on Skylake.

On Wayland, this also creates no new configs, and therfore breaks no
existing apps. (I tested with mesa-demos' eglinfo and es2gears_wayland
on Skylake). The reason differs from GLX, though. In
dri2_wl_add_configs_for_visual(), the format table contains only
B8G8R8X8, B8G8R8A8, and B5G6B5; and dri2_add_config() correctly matches
EGLConfig to format by inspecting channel masks.

On Android, in Chrome OS, I tested this on a Broxton device. I confirmed
that the Google Play Store's EGLSurface used HAL_PIXEL_FORMAT_RGBA_8888,
and that an Asteroid game's EGLSurface used HAL_PIXEL_FORMAT_RGBX_8888.
Both apps worked well. (Disclaimer: I didn't test this patch on Android
with Mesa master. I backported this patch series to an older Android
branch).

i965: Add a RGBX->RGBA fallback for glEGLImageTextureTarget2D()

This enables support for importing RGBX8888 EGLImage textures on
Skylake.

Chrome OS needs support for RGBX8888 EGLImage textures because because
the Android framework produces HAL_PIXEL_FORMAT_RGBX8888 winsys
surfaces, which the Chrome OS compositor consumes as dma_bufs.  On
hardware for which RGBX is unsupported or disabled, normally core Mesa
provides the RGBX->RGBA fallback during glTexStorage.  But the DRIimage
code bypasses core Mesa, so we must do the fallback in i965.

mesa: Add _mesa_format_fallback_rgbx_to_rgba() [v2]

The new function takes a mesa_format and, if the format is an alpha
format with a non-alpha variant, returns the non-alpha format.
Otherwise, it returns the original format.

Example:
  input -> output

  // Fallback exists
  MESA_FORMAT_R8G8B8X8_UNORM -> MESA_FORMAT_R8G8B8A8_UNORM
  MESA_FORMAT_RGBX_UNORM16 -> MESA_FORMAT_RGBA_UNORM16

  // No fallback
  MESA_FORMAT_R8G8B8A8_UNORM -> MESA_FORMAT_R8G8B8A8_UNORM
  MESA_FORMAT_Z_FLOAT32 -> MESA_FORMAT_Z_FLOAT32

i965 will use this for EGLImages and DRIimages.

v2 (Jason Ekstrand):
 - Use mako
 - Rework to be easier to read
 - Write directly to the output file
